TopIn the recent 20 years, TCM diagnostic information extraction and processing are mainly centered on the pulse and tongue(Weiwu, Zheli, & Qun, 2005; Haixia, Yiqin, & Fufen, 2005). For the last five years, tongue information processing technology has a great development and its practically clinical application has been started. However, for such complex information as eyes’ movement which is also important in TCM diagnosis, the research on the extraction and Spirit diagnosing by eye features is still at a blank stage. There is no research report in this field till now.
The concept and model of association rules were first raised by Agrawal et al. (1993). Since then, there have been a series of association rule mining algorithms. Agrawal and Srikant (1994) proposed Apriori algorithm, which is used for mining association rules. Although the algorithm can generate all the association rules, it is an inefficient mining algorithm. As a result, some of the improved Apriori algorithms have been emerged. There are: Hash algorithm (Park, Chen, & Yu, 1995), Block technique Algorithm (Savasere, Omiecinski, & Navathe, 1995), Sampling algorithm (Toivonen, 1996), Dynamic Item set technique Algorithm (Brin, 1997), Incremental mining algorithm (Cheung, 1996), Parallel and Distributed mining algorithms, Associated with Database System Integration mining algorithms.
